+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## What changes from the original create-react-app
+1. Adding server.js using Express to serve the client app and providing a `negotiate` endpoint for the client to get the `Client Access URI`
+1. adding a npm command `npm run server` to build the client app and running the Expressserver
+1. update src/App.js to create a WebSocket connection
+
+
+## How to run
+```
+export WebPubSubConnectionString=”Your_Connection_String”
+npm install
+npm run server
+```
